Question

Write the following sets in the
roaster form.
i) D= {t:t^3=t€R}
ii) E={W:w-2/w+3}=3,W€R}
iii) F={x:x^4-5x^2+6=0,x€R}
​

Answer 1

Step-by-step explanation:

B = { 0, 1 }

Explanation:

The roster form

set B= {x/x²=x, x€R }

B = { 0 , 1 }

_____________________

x² = x

i) if x = 0 then(0)² = 0

ii) if x = 1 then 1² = 1

Answer 2

Step-by-step explanation:

i) D = {t | t3 = t, t ∈ R}

(ii) E = {w | (w-2)/(w+3) = 3, w ∈ R}

(iii) F = {x | x4 – 5x2 + 6 = 0, x ∈ R}
